Solution Overview

Problem

Existing devices for containing soiled objects, such as diapers, lack modular design and maintenance options, making them inefficient for long-term use and hygiene maintenance.

Innovation Solution

A device with a detachable body and sleeve system, where the sleeve can be replaced or cleaned separately, and a spring ring mechanism for easy attachment and detachment, allowing for flexible use and hygiene management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the device uses a fixed integrated design, then the structure is simple, but maintenance and hygiene are difficult

Engineering Contradiction:
ImprovemaintenanceVSAvoidstructure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The device is divided into separate functional modules: a removable body (piston), a sleeve, and a container. The body can be detached from the sleeve for separate cleaning and maintenance, while the sleeve remains in the container. This segmentation allows easy maintenance of hygiene-critical components without disassembling the entire device.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the device uses a non-detachable design, then the structure is stable, but replacement and cleaning are difficult

Engineering Contradiction:
ImprovecleaningVSAvoidstructure
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The body is designed as a separate removable component from the sleeve, allowing it to be detached for thorough cleaning or replacement while the sleeve remains in place within the container, maintaining structural stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The body is inserted into and nested within the sleeve, with the sleeve itself being insertable into the container. This nested arrangement allows easy removal of the body for cleaning while the sleeve provides structural support within the container.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the device uses a permanent attachment system, then the connection is strong, but replacement and maintenance are complex

Engineering Contradiction:
ImprovereplacementVSAvoidconnection
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The attachment system transitions from a permanent fixed connection to a dynamic removable connection. The body can be easily detached from and reattached to the sleeve multiple times, providing adaptability for replacement and maintenance while maintaining a strong sealed connection during use through the piston-rim interface.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enhances user convenience by enabling easy maintenance, hygiene, and extended use through modular design, improving the efficiency and odor/liquid containment of the device.

Implementation Method 1

the body can move downwards in the tubular element under the influence of the force of gravity in order to push the object into the container

Methodology Applied
Scientific EffectGravity: Gravitation

Implementation Method 2

When the ring is subsequently released again, it can spring back to its starting position and lock itself in place within the cylinder

Methodology Applied
Scientific EffectElasticity: Elasticity

AI summary

The device (l) comprises a container (2) and a cover (3), said cover including a hollow tubular element (7) open at at least one end (5, 6), in which a body (8) capable of reciprocating motion is provided, said cover being pivotable with respect to the container between a first position, in which an object can be placed into the tubular element , and a second position, in which the body can move downwards in the tubular element under the influence of the force of gravity to push the object into the container. The device further comprises sleeve (18) of a flexible material arranged within the tubular element, the body being connected to the sleeve near the closed end of the sleeve and the sleeve being attached to the tubular element along its circumferential edge.
